don't use a wireless fm transmitter. they all suck. if you really wanna keep the factory unit then use a wired fm modulator. plugs in through the antenna. same concept with better results. you'll just need the modulator and forward and reverse antenna adapters to make it work. however i would still recommend just doing an aftermarket headunit. the best options and not much more cost for a basic one. will also get you better sound quality overall.
